WebUse Green's Theorem to calculate the area of the disk D of radius r defined by x 2 + y 2 ≤ r 2. Solution: Since we know the area of the disk of radius r is π r 2, we better get π r 2 for our answer. The boundary of D is the circle of radius r. We can parametrized it in a counterclockwise orientation using c ( t) = ( r cos t, r sin t), 0 ≤ t ≤ 2 π. WebMar 24, 2024 · Green's theorem is a vector identity which is equivalent to the curl theorem in the plane. Over a region in the plane with boundary , Green's theorem states (1) where the left side is a line integral and the right side is a surface integral. This can also be written compactly in vector form as (2) green card waiting time indians
